【発明の属する技術分野】
本発明は重装備運転室の前面下部に着脱可能に設けられる下部ガラスを作業環境に応じて分離する場合、運転室内に安全に保管しておくために運転室出入り扉の内側面に設けられる重装備運転室の下部ガラス保管機構に関するものである。
【０００２】
【従来の技術】
従来重装備運転室の下部ガラス保管機構は、図１に示したように、運転室(１０)の前面下部に着脱可能に設けられる下部ガラス(１００)を作業環境に応じて分離する場合、該下部ガラス(１００)をロッキング仕掛け(２０)を用い運転室の後方ガラス(１１)に重ね固定しておくことができるように構成されるか、又は、図示なしの運転室(１０)を形成するパネルの内側面に固定しておけるように構成されていた。
【０００３】
説明なしの符合１２は重装備の行動制御用調整レバ−が設けられたコントロ−ルボックスである。
【０００４】
しかしながら、上述のように下部ガラス(１００)を運転室(１０)の後方ガラス(１１)に重ね保管できるように構成された従来の重装備運転室の下部ガラス保管機構は下部ガラス保管中に重装備が引っ繰り返る等の突発的な危険状況が発生する場合、ドライバ−の緊急待避を妨げる恐れがあり、また、下部ガラス(１００)の保管位置がドライバ−の頭位に位置し、事故発生の際、ガラス(１００)が外部ショックによりドライバ−の上体に真っ直ぐ飛び込み、致命的な人命被害を受けることがあり得り、保管のために狭苦しい運転室内において、重量（６-７kg 位)の下部ガラス(１００)を取り付ける過程における不注意により落し破損する場合、オペレ−タが甚だしい怪我をする恐れがあるだけではなく、事故処理にも極めて不便であった。
【０００５】
なお、従来重装備の運転室の下部ガラス保管具の中には、下部ガラスを運転室の側面に保管できるように構成された場合もあったが、従来重装備運転室の下部ガラス保管機構が設けられる場合には、国際規格(ISO)から求められる重装備運転室の室内幅(９２０mm)仕様を充足するように、運転室の規格を拡大すべきな問題点があって、下部ガラスの鋭いエッジがドライバ−身近に位置するので、安全事故の危険が常存したのであり、下部ガラスがドライバ−の頭位に位置し、事故発生の際、ドライバ−の該下部ガラスの破片により致命的な怪我をするという問題点があった。
【０００６】
【発明が解決しようとする課題】
本発明は重装備の運転室前面下部に設けられ、作業環境に応じて分離される重装備運転室の下部ガラスを運転室出入り扉の内面下方に安全に保管しておくことができることにより、事故発生の際、人命被害を減らすことができ、下部ガラスの脱着が容易な重装備運転室の下部ガラス保管機構を提供することにその目的がある。
【０００７】
【課題を解決するための手段】
本発明は、分離可能な重装備運転室の下部ガラスの運転室内に臨時保管のために設けられる重装備運転室の下部ガラス保管機構において、
前記運転室出入り扉の内側面下部に取り付けられるものであって、下部ガラスの下端部を嵌め込めるように上方に解放された安置溝を形成し、該安置溝に嵌め込まれた下部ガラスを支持する下部ブラケット ;

前記運転室出入り扉の内面における上部に設けられ、前記下部ブラケットの安置溝に嵌め込まれた状態において、前記上部ブラケットに密着の下部ガラスの外面上部を解除可能に支持するロッキング仕掛けを含んで成り、
前記ロッキング仕掛けは、前記運転室出入り扉の内面に取り付けられる固定台 ; 前記固定台に該後端が回転可能に結合されるハンドル ; 前記ハンドルの内側面から突き出され前記ハンドルと一体に回転しながら前記下部ガラスの外側面を支持するか解除する支持具 ; 及び前記ハンドルの回転を拘束するハンドル拘束手段を含んでなることを特徴とする。
【０００９】
なお、望ましい特徴によると、前記ハンドル拘束手段は、前記固定台に回転及び、軸方向へ移動可能に軸結合され、該先端に前記ハンドルが軸方向への移動が可能に結合され、前記ハンドルを制限の角範囲内において下方回転が可能に前記固定台に固定する拘束棒と ; 前記拘束棒を前記固定台に対して弾性支持し前記拘束棒の最大に下方回転角において、拘束棒の凸部が弾性支持による前記拘束棒の軸方向への移動により前記固定台の凹部に嵌め込まれるようにする圧縮バネ ;を含んでなる。
【００１０】
合わせて、以上のような構成要素は前記上部ブラケットが運転室内のコントロ−ル装置の上端より低く位置するように構成することが望ましい。
【００１１】
【発明の実施の形態】
以下、本発明の望ましい実施例を添付の図面を参照しより詳しく説明する。
【００１２】
本発明による重装備運転室の下部ガラス保管機構は重装備運転室の下部ガラスを作業環境に応じて分離する場合、運転室内に安全に保管できるように構成されたものであって、図２及び図３に示したように、前記運転室出入り扉(１３)の内側面下部に取り付けられ、上方に解放された安置溝(１a)を形成する下部ブラケット(１)、前記下部ブラケット(１)の上に設けられ、該表面にレバ−材の緩衝材(２a)付き上部ブラケット(２) ; 前記上部ブラケット(２)と共に前記運転室出入り扉(１３)に固定され、前記下部ブラケット(１)と上部ブラケット(２)との間に嵌められた下部ガラス(１００)を解除可能に拘束するロッキング仕掛け(３)等から構成される。 以上の構成らは事故発生の際、下部ガラス(１００)がドライバ−に致命的な被害を与えないようにするために、それらの中に最上段に位置する上部ブラケット(２)が運転席に座るドライバ−の腰より下に位置するように設けられる。
【００１３】
前記下部ブラケット(１)は図３と４に示したように、運転室出入り扉(１３)の内側面下部に固定・付着され、上方に解放した安置溝(１a)を形成し、該安置溝(１a)に嵌め込まれた下部ガラス(１００)を解除可能に拘束するロッキング仕掛け(３)等から構成される。 以上の構成らは事故発生の際、下部ガラス(１００)がドライバ−に致命的な被害を与えないようにするために、それらの中に最上段に位置する上部ブラケット(２)が運転席に座る運転者の腰より下方に位置するように設けられる。
【００１４】
前記下部ブラケット(１)は図３と４に示したように、運転室出入り扉(１３)の内側面の下部に固定、取り付けられ、上方に解放した安置溝(１a)を形成し、該安置溝(１a)に嵌められた下部ガラス(１００)の下部を支えるものであって、望ましくはショックから下部ガラス(１００)を保護できるようにゴム製により成形される。 前記安置溝(１a)は該安置溝(１a)に嵌められる下部ガラス(１００)に対して外側に向かいトルクが作用できる構造を有するように成形される。
【００１５】
上部ブラケット(２)は図３と５に示したように、前記下部ブラケット(１)に嵌められる運転室出入り扉(１３)の方に密着される下部ガラス(１００)の内面上部を支持するものであり、下部ガラス(１００)に接する表面にはショック吸収のためのゴム製の緩衝材(２a)が取り付けられる。
【００１６】
ロッキング仕掛け(３)は図３に示したように、前記上部ブラケット(２)の表面に接し、該上部ブラケット(２)と共に出入り扉(１３)に固定するものであって、図６と７に示したように、前記上部ブラケット(２)と共に出入り扉(１３)の内面に取り付けられる固定台(３１)、前記固定台(３１)に制限角度の範囲内において、下方回転が可能に設けられるハンドル(３０)、前記ハンドル(３０)の回転を選択的に拘束するハンドル拘束手段、そして、前記ハンドル(３０)の内側面から突き出され、下部ガラス(１００)の外側面上部を直接支持する弾性材質の支持具(３２)から構成されている。
【００１７】
ハンドル拘束手段は図８と９に示したように、前記固定台(３１)の中央に形成された通穴(３１a)に嵌め込まれ、該先端に結合されたハンドル(３０)を固定台(３１)に回転可能に繋げる拘束棒(３３)と該拘束棒(３３)を前記固定台(３１)に対して弾性支持する圧縮バネ(３４)から構成される。 拘束棒(３３)の後端には拘束棒(３３)の離脱防止のための離脱防止凸部(３３a)が設けられ、該離脱防止凸部(３３a)の一側には軸方向に突き出された掛け凸部(３３b)が成形される。 そして、前記固定台(３１)には拘束棒(３３)の最大下方角度において前記掛け凸部(３３b)と位相が等しくなる掛け溝(３１b)が形成される。
【００１８】
このような構成により前記ハンドル拘束手段(３１b, ３３, ３４, ３３b)は、ハンドル(３０)が最大に下方回転した場合、すなわちハンドル(３０)と共に回転した支持具(３２)が下部ブラケット(１)に嵌め込まれた下部ガラス(１００)の外側面を支持するようになる場合、図８に示したように、ハンドル(３０)と共に回転された拘束棒(３３)の掛け凸部(３３b)と固定台(３１)に掛け溝(３１b)が相互位相が等しくなるにつれ、拘束棒(３３)が圧縮バネ(３４)の弾性力により軸方向へ移動し拘束棒(３３)の掛け凸部(３３b)が固定台(３１)の掛け溝(３１b)に嵌め込まれることにより、拘束棒(３３)を固定台(３１)に拘束し結果的にハンドル(３０)を回転されないように拘束する。
【００１９】
本発明による重装備運転室の下部ガラス保管機構が上述のような構成からなることにより、重装備運転室の前面下部から分離した下部ガラス(１００)を次のような方法により運転室出入り扉(１３)の内面に取り付け又は脱去できる。
【００２０】
下部ガラス(１００)を分離し本発明による重装備運転室の下部ガラス(１００)保管機構として運転室出入り扉(１３)に固定しようとする場合、まず、ハンドル(３０)を最大上向回転角度に上向回転させた状態において、下部ガラス(１００)を下部ブラケット(１)に嵌め込み、出入り扉(１３)の方に押し該下部ガラス(１００)の内側面上部が上部ブラケット(２)の緩衝材(２a)に密着されるようにし、下部ガラス(１００)を下部ブラケット(１)と上部ブラケット(２)との間に臨時固定する。 次いで、ハンドル(３０)を最大下向回転角度に回転させると、該ハンドル(３０)と共に回転される支持具(３２)の先端が下部ガラス(１００)の外面上部に密着しながら下部ガラス(１００)の上部を支持するようになる。次いで、上、下部ブラケットとの間に嵌め込まれた下部ガラス(１００)をハンドル(３０)の支持具(３２)として離脱されないように固定できる。この時、ハンドル拘束手段（３１b,３３,３４,３３b）は、ハンドル(３０)と共に最大下向回転角度に回転された拘束棒(３３)の掛け凸部(３３b)と固定台(３１)に形成された掛け溝(３１b)の位相が相互等しくなることにつれ、拘束棒(３３)が圧縮バネ(３４)の弾性により外側に向かい軸方向に移動するようになり、図８のように、掛け凸部(３３b)が固定台(３１)の掛け溝(３１b)に嵌め込まれることにより、拘束棒(３３)すなわち、ハンドル(３０)を固定台(３１)に拘束し支持具(３２)を下部ガラス(１００)を支持している状態において任意に回転しないように拘束する。
【００２１】
反対に、重装備運転室の下部ガラス保管機構に固定された下部ガラス(１００)を脱去しようとする場合には、まずハンドル(３０)を握り親指で外側に突き出た拘束棒(３３)の先端部を押し、図９に示したように、該拘束棒(３３)の掛け凸部(３３b)が固定台(３１)の掛け溝(３１b)から抜け出るようにする。 次いで、拘束棒(３３)の先端部を押した状態のままに、即ち拘束棒(３３)が自由に回転できる状態において、前記ハンドル(３０)を下部ガラス(１００)から外れるように図７の点線のように上向回転させると、支持具(３２)がハンドル(３０)と共に下部ガラス(１００)から外れ、下部ガラス(１００)に対する拘束を解除するようになる。従って、下部ブラケット(１)にのみ単純に嵌め込まれ脱去可能な状態となる下部ガラス(１００)を持ち上げ出入り扉(１３)から脱去できる。
【００２２】
【発明の効果】
以上から詳しく説明したような本発明による重装備運転室の下部ガラス保管機構によると、作業環境に応じて分離された運転室前面下部ガラスをドライバ−の作業位置より低い出入り扉内面の下側に保管できるので、事故発生の際、臨時保管の下部ガラスによる人的被害を減らし、ドライバ−の安全度を改善できる。 なお、本発明による重装備運転室の下部ガラス保管機構は出入り扉の内面に設けられるので、出入り扉を解放した状態において、他の部品の干渉なしに室外で下部ガラスを脱着でき、なおロッキング仕掛けの操作が極めて簡便で、下部ガラスの脱着が容易であるというメリットがある。
